+
+    nfs_exports: []
+
+A list of exports which will be placed in the `/etc/exports` file. See Ubuntu's simple [Network File System (NFS)](https://help.ubuntu.com/14.04/serverguide/network-file-system.html) guide for more info and examples. (Simple example: `nfs_exports: { "/home/public    *(rw,sync,no_root_squash)" }`).
